Seleucĭdæ, a surname given to those monarchs who sat on the throne of Syria, which was founded by Seleucus the son of Antiochus, from whom the word is derived. The era of the Seleucidæ begins with the taking of Babylon by Seleucus, B.C. 312, and ends at the conquest of Syria by Pompey, B.C. 65. The order in which these monarchs reigned is shown in the account of Syria. See: [Syria].

Seleucis, a division of Syria, which received its name from Seleucus, the founder of the Syrian empire after the death of Alexander the Great. It was also called Tetrapolis, from the four cities which it contained, called also sister cities; Seleucia called after Seleucus, Antioch called after his father, Laodicea after his mother, and Apamea after his wife. Strabo, bk. 16.

Seleucus I., one of the captains of Alexander the Great, surnamed Nicator, or Victorious, was son of Antiochus. After the king’s death, he received Babylon as his province; but his ambitious views, and his attempt to destroy Eumenes as he passed through his territories, rendered him so unpopular, that he fled for safety to the court of his friend Ptolemy king of Egypt. He was soon after enabled to recover Babylon, which Antigonus had seized in his absence, and he increased his dominions by the immediate conquest of Media, and some of the neighbouring provinces. When he had strengthened himself in his empire, Seleucus imitated the example of the rest of the generals of Alexander, and assumed the title of independent monarch. He afterwards made war against Antigonus, with the united forces of Ptolemy, Cassander, and Lysimachus; and after this monarch had been conquered and slain, his territories were divided among his victorious enemies. When Seleucus became master of Syria, he built a city there, which he called Antioch in honour of his father, and made it the capital of his dominions. He also made war against Demetrius and Lysimachus, though he had originally married Stratonice the daughter of the former, and had lived in the closest friendship with the latter. Seleucus was at last murdered by one of his servants called Ptolemy Ceraunus, a man on whom he bestowed the greatest favours, and whom he had distinguished by acts of the most unbounded confidence. According to Arrian, Seleucus was the greatest and most powerful of the princes who inherited the Macedonian empire after the death of Alexander. His benevolence has been commended; and it has been observed, that he conquered not to enslave nations, but to make them more happy. He founded no less than 34 cities in different parts of his empire, which he peopled with Greek colonies, whose national industry, learning, religion, and spirit, were communicated to the indolent and luxurious inhabitants of Asia. Seleucus was a great benefactor to the Greeks; he restored to the Athenians the library and statues which Xerxes had carried away from their city when he invaded Greece, and among them were those of Harmodius and Aristogiton. Seleucus was murdered 280 years before the christian era, in the 32nd year of his reign, and the 78th, or, according to others, the 73rd year of his age, as he was going to conquer Macedonia, where he intended to finish his days in peace and tranquillity in that province where he was born. He was succeeded by Antiochus Soter. Justin, bk. 13, ch. 4; bk. 15, ch. 4; bk. 16, ch. 3, &c.Plutarch, Demosthenes.—Pliny, bk. 6, ch. 17.—Pausanias, bk. 8, ch. 51.—Josephus, Antiquities, bk. 12.

Seleucus II., surnamed Callinicus, succeeded his father Antiochus Theus on the throne of Syria. He attempted to make war against Ptolemy king of Egypt, but his fleet was shipwrecked in a violent storm, and his armies soon after conquered by his enemy. He was at last taken prisoner by Arsaces, an officer who made himself powerful by the dissensions which reigned in the house of the Seleucidæ, between the two brothers Seleucus and Antiochus; and after he had been a prisoner for some time in Parthia, he died of a fall from his horse, B.C. 226, after a reign of 20 years. Seleucus had received the surname of Pogon, from his long beard, and that of Callinicus, ironically to express his very unfortunate reign. He had married Laodice the sister of one of his generals, by whom he had two sons, Seleucus and Antiochus, and a daughter whom he gave in marriage to Mithridates king of Pontus. Strabo, bk. 16.—Justin, bk. 27.—Appian, Syrian Wars.

Seleucus III., succeeded his father Seleucus II. on the throne of Syria, and received the surname of Ceraunus, by antiphrasis, as he was a very weak, timid, and irresolute monarch. He was murdered by two of his officers, after a reign of three years, B.C. 223, and his brother Antiochus, though only 15 years old, ascended the throne, and rendered himself so celebrated that he acquired the name of the Great. Appian.

Seleucus IV., succeeded his father Antiochus the Great on the throne of Syria. He was surnamed Philopater, or, according to Josephus, Soter. His empire had been weakened by the Romans when he became monarch, and the yearly tribute of 1000 talents to those victorious enemies concurred in lessening his power and consequence among nations. Seleucus was poisoned after a reign of 12 years, B.C. 175. His son Demetrius had been sent to Rome, there to receive his education, and he became a prince of great abilities. Strabo, bk. 16.—Justin, bk. 32.—Appian.

Seleucus V., succeeded his father Demetrius Nicator on the throne of Syria, in the 20th year of his age. He was put to death in the first year of his reign by Cleopatra his mother, who had also sacrificed her husband to her ambition. He is not reckoned by many historians in the number of the Syrian monarchs.

Seleucus VI., one of the Seleucidæ, son of Antiochus Gryphus, killed his uncle Antiochus Cyzicenus, who wished to obtain the crown of Syria. He was some time after banished from his kingdom by Antiochus Pius son of Cyzicenus, and fled to Cilicia, where he was burnt in a palace by the inhabitants, B.C. 93. Appian.Josephus.

Seleucus, a prince of Syria, to whom the Egyptians offered the crown of which they had robbed Auletes. Seleucus accepted it, but he soon disgusted his subjects, and received the surname of Cybiosactes, or Scullion, for his meanness and avarice. He was at last murdered by Berenice, whom he had married.——A servant of Cleopatra the last queen of Egypt, who accused his mistress, before Octavianus, of having secreted part of her jewels and treasures.——A mathematician intimate with Vespasian the Roman emperor.——A part of the Alps.——A Roman consul.——A celebrated singer. Juvenal, satire 10, li. 211.——A king of the Bosphorus, who died B.C. 429.
